The interview process consisted of a screening, technical, and a culture interview. You have two other meetings, but I would not deem these as interviews so I will omit them (you only have these conversations if you are likely being offered).
During the screening, you review your resume and general background. You'll answer some questions regarding your resume as it pertains to the position, in my case, it was related to my transition from engineering to product.
The technical screening was a unique interview meant to demonstrate the required previous engineering requirement for the position. It was a simple logic conversation that anyone with any technical background could do without much preparation. I would describe the conversation was discussing I/O functionality and the rationality behind your choices.
The final conversation is a culture interview as it pertains to the position. This is a typical interview where you meet folks you will work with. I answered questions about how I have previously handled delicate product situations before, par for the course for this position.
